基于DSP的网络摄像机硬件设计和仿真

详细说明了基于TITMS320DM642DSP芯片的网络摄像机的硬件设计,并针对DSP系统实现中所涉及到的高速数字电路设计问题,如时序问题、信号完整性问题,通过采用IBIS模型,在HyperLynx仿真软件平台上布线前进行仿真,利用仿真结果作为布线的约束,并在布线后进行仿真,确保了正确性。实践证实,在高速设计中进行正确的时序分析及仿真可以保证高速PCB设计的质量和速度。

The Design and Simulation of IP Camera Based on DSP

This paper gives a detail design of IP Camera based on TMS320DM642,a kind of DSP chip provided by Texas Instruments,and because of the problems of high speed digital circuits that involve in the implementation of the DSP system,such as timing and signal integrity,we used the IBIS model to simulate before PCB layout,and generate rules from the results as constraints to guide PCB layout,after PCB layout,we did simulation to make sure the accuracy of the system.The experiment showed that:do simulation during high speed circuit design can improve the quality and reduce the design time greatly.
